METHOD O F RAISING WATER.

Specification of Letters Patent No. 16,669, dated February 17, 1857.

'lo all whom it may concern:

Be it known that I, DANIEL K. VVINDER, of Cincinnati, Hamilton count-y, Ohio, have invented a new and useful Apparatus for Raising Vater; and I hereby declare the following to be a full, clear, and exact description thereof, reference being had to the annexed drawing, making a part of this specification, wherein my device is represented by a longitudinal section.

The object of my invention is to provide a cheap, easily operated and effective means of raising water from a cistern in either large or small quantities at pleasure.

(a) is a cistern from whose cove-r (b) a post or staffl (cl depends vertically into the cistern. To this post near its lower end is attached a vessel called by me the reservoir formed with two concentric cylinders (l) (e) having their annular interval closed at top and bottom. The central space within the inner cylinder is open at top but at bottom is provided with a floor (g) having a valve aperture (h) opening upward. Near the lower end of the inner cylinder (c) is a valve aperture opening from the central space into the annular space of the reservoir.

Formed to slide up and down snugly but freely within the central space of the reservoir is a cylindrical vessel (j) called by me the plunger. This plunger and the inclosing central space of the reservoir are not ground or otherwise expensively fitted to each other but approach with suflicient closeness for the thin film of water to form a joint. The plunger (j) is closed at the top and bottom its floor having a valve aperture (lc) opening upward.

Made fast to the top of the plunger and extending vertically downward to near its floor, and upward to a convenient height above the cistern cover is a pipe (l) terminating at top in a spout and handle Projecting also through the top of the plunger to near its floor, is a similar pipe (o) whose upper end extending a short distance above the top of the plunger is connected by a flexible tube (p) with the lower part of the annular chamber, the communication at the lower end being completed by a short pipe (g) to which the lower end of the tube (p) is secured. This pipe is ordinarily closed by a stop cock (r) which may shut automatically by a weighton its handle or otherwise. From the handle of this cock a rod or cord (s) extends upward above the cistern cover where it terminates in a ring or handle (t) by which to lift the cord and by that means open the cock when desired.

Projecting laterally from one side of the plunger is an arm (u) which, being forked, straddles the post (c) and impinging against a pin (o) the plunger is thereby prevented from escaping out of the centra-l space.

Before immersion in the water both reservoir and plunger are full of air but when immersed, portions of water rising through the described valves into these vessels crowd their contained air into the upper parts until the expansive force of the air within balances the weight of the hydrostatic column without.

More than one suspending post may be employed, if desired.

The operation is as follows: When water is desired by the bucket-full the tube (l) and plunger are depressed by the hand or foot of the operator, compelling the water contained in the central space to enter the plunger and the annular chamber of the reservoir in two separate portions. Of these portions, that which enters the plunger being opposed by the reaction of its contained air is driven up the tube (l) and escapes through the spout the foot being then withdrawn the plunger rises to its uppermost position, and its contained air resumes its former dimensions. Meanwhile the valve closing, that part of the water which was forced into the reservoir, is there retained under pressure of the confined air for future or present use being especially serviceable and intended for small and frequent supplies. If for example itbe desired to fill a tumbler merely; the object may be attained without waste of water or superfluous effort by the operator, the eX: ertion being only that of opening the cock (r) for an instant, by lifting the ring (t), which results in the escape from the annular chamber of the desired volume of water oistern, the reserve chamber is found constantially as described; of annular reserstantly eiective for all quantities less than Voir With the plunger tube (l),
